Estimation of Standard Operation Time of Flight Legs Based on Clustering and Probability Analysis

A clustering algorithm and a probability statistics method were applied to different phases of a flight to analyze operation time during aircraft ground taxiing and airborne flight.And the clustering pattern,distribution characteristics and dynamically changing rules of the two phases were identified.Further,an estimate method was established to measure operation time of flight legs,with creative steps of calculating individual segment separately and then integrating them accordingly.The method can both objectively and dynamically measure operation time,and accurately reflect real situation.It helps to better utilize airport slot resources and provides a strong support for air traffic flow management when scheduling flight plan in strategic and pre-tactic phases.

First Forum on China Casting Quality Standards & Overview of Revision History of China's National/Industrial Standards for Foundry Operations

Both national and local governments have been paying great attention to the work of industrial standardization with the enormous increase in international trade after China joined WTO. According to the standards revising plan of Standardization Administration Committee of China (SAC),TC54 has already revised a series of national standards and industrial standards for foundry operations,and proposed some new ones. As a result,some old fashioned standards containing low-level techniques have been gradually discontinued or replaced with new versions.……

Operations Support Systems Standards:Status Quo and Trends

The emerging of diversified new telecommunications technologies leads to a continuous change of telecom networks. Consequently, the operations support systems of telecommunications operators are facing structure adjustments as well as new systems construction. In this situation, new generation operations support systems standards are urgently required. Several standardization organizations have made substantial progress in the study of the new generation standards, such as ITU' s study on Next Generation Network (NGN) management, TMF's on New Generation Operations Systems and Software (NGOSS) and CCSA's on network management standards. However, the existing operations support systems face the challenges of architecture improvement, change of the focus of operations support, orientation of customers' demands and technology evolution.

An effective snakebite first aid training method for medics in the Chinese troops: a RCT

Background:Snakebites can lead to lifelong consequences and is one of the main causes of death among military troops worldwide.However,few Chinese military medics know the proper first aid procedures for snakebites.Therefore,this study aimed to explore the impact of the Standard Operation Procedure(SOP)and checklist on Chinese military medics’ability to manage snakebite first aid.Methods:This study was a prospective single-blind randomized controlled trial conducted in a military medical university of China from May to June 2017.A questionnaire-based survey was performed to collect the participants’socio-demographic profiles before the baseline measurement.During the baseline measurement,participants were requested to provide corresponding first aid that was responsive to the simulative situation portrayed by the standardized patients(SPs)and the evaluators then scored their performances according to a checklist for snakebite first aid scoring table.After the baseline measurement,they were randomly assigned to one of three intervention groups after stratification according to their baseline performance scores:group A received a self-learning course with textbooks(n=27),group B received a self-learning training on the SOP and checklist(n=27)and group C was engaged in an interactive discussion panel regarding the SOP and checklist(n=26).After the interventions,participants received outcome measurements about snakebite first aid key points capability from the same evaluator and SP for each group to avoid observational error.The reviewers were blinded about the grouping in the trial.Results:The baseline measurement yielded no significant difference(H=1.647,P=0.439)among the three groups.The post-intervention scores were higher than the pre-intervention scores for all three(A,B and C)groups(P=0.008,P<0.001 and P<0.001,respectively).There was significant difference of the post-intervention scores among the three groups(F=8.841,P<0.001).Both post-intervention scores of group B and group C were higher than that of group A(P<0.001 and P=0.001,respectively),but no difference was found between group B and C(P=0.695).The acceptance questionnaire score of SOP and checklist was mostly very satisfied,as the final scores of group B and group C were 4.62±0.61 and 4.82±0.45,respectively.Conclusions:In this study,the implementation of an SOP and checklist for snakebite first aid was shown to update and improve first aid treatment concepts in military medics.These intervention methods played an important role in improving the medics’cognition and understanding of snakebite first aid.Therefore,this finding suggests that SOP and checklist training should be further implemented in Chinese troops for snakebite care.

Jordan Maps on Standard Operator Algebras

Let A be a standard operator algebra on a Banach space of dimension 〉 1 and B be an arbitrary algebra over Q the field of rational numbers. Suppose that M ： A → B and M^＊ ： B → A are surjective maps such that {M（r（aM^＊（x）＋M^＊（x）a））=r（M（a）x＋xM（a））, M^＊（r（M（a）x＋xM（a）））=r（aM^＊（x）＋M^＊（x）a） for all a ∈ A, x ∈ B, where r is a fixed nonzero rational number. Then both M and M^＊ are additive.

Strong 3-Commutativity Preserving Maps on Standard Operator Algebras

Let X be a Banach space of dimension ≥ 2 over the real or complex field F and A a standard operator algebra in B（X）. A map Ф ： A→A is said to be strong 3-commutativity preserving if [Ф（A）, Ф（B）]a = [A, B]3 for all A, B C .4, where [A, B]3 is the 3-commutator of A, B defined by [A, B]3 = [[[A, B], B], B] with [A, B] = AB - BA. The main result in this paper is shown that, if Ф is a surjective map on A, then Ф is strong 3-commutativity preserving if and only if there exist a functional h ： A→F and a scalar λ∈F with λ^4 = 1 such that Ф（A） = λA ＋ h（A）I for all A ∈A.

Forensic Science and its Limitations in Rape and Murder Cases in India

Forensic science plays a significant role in crime scene analysis and other evidence collection(such as clothes,cigarette butts,blood,semen,hair,etc.,)to scientifically establish the accused’s guilt.In rape and murder cases,DNA tests confirm the victim’s identity.It provides certain evidence that is helpful in the speedy investigation and conclusion of a trial.However,it is not a foolproof science and it has certain limitations.Hence,the first responders,such as the Crime Laboratory Ultimate Evidence System team and the forensic experts,must keep these limitations in mind during sample collection and examination,otherwise,it may lead to incorrect results.Such incorrect results may be obtained due to insufficient sample quantity,improper collection methods,or delay in an examination.It is highly recommended to implement standard operating procedure guidelines,failing which the admissibility of such forensic evidence to prove beyond all reasonable doubts is at stake.Accordingly,the court shall acquit the accused giving him the benefit of doubt.This article focuses on the applicability and limitations of forensic science in the Indian Criminal Justice System and the need to adopt due protocols to yield viable results.

We show that a bijective map Ф ： A →A preserves the Lie-skew product AB - BA＊ if and only if there is a unitary or conjugate unitary operator U ∈A（H） such that Ф（A） = UAU＊ for all A ∈ A, that is, Фis a linear ＊ -isomorphism or a conjugate linear ＊-isomorphism.

Pakistan’s experience with risk assessment training and implementation of concepts from the 4th edition of the WHO laboratory biosafety manual

Introduction:The cyclical process of hazard identification,risk assessment,risk mitigation,and review is a key step in developing a biorisk management(BRM)system.This paper describes how this process was initiated in two laboratories in Pakistan using a unique model of blended learning.Methods:A training needs analysis showed that the staff had very little knowledge of BRM systems.A workshop using a unique blended model was conducted in which virtual and in-presence learning occurred simultaneously.This workshop aimed to train the participants by applying two key concepts from the World Health Organization Laboratory Biosafety Manual 4th edition:1)the cyclical process of risk assessment and 2)mapping the core biorisk and establishing heightened control measures in the laboratories of the participants based on the risk assessment.All scenarios and examples used in the training were from the participants’laboratory work processes.Results:Prior to this project,no risk assessment was conducted in these laboratories.After the workshop,a risk assessment was performed for six work processes.In addition,seven core requirements and three heightened control measures were mapped,a biorisk officer was appointed,and a biosafety committee was convened.Furthermore,a biorisk manual,a biological waste management plan,an occupational health center,and a system for audits and inspections are being developed.Discussion and conclusion:BRM training is not a one-time effort;it has to be strengthened to ensure the development and implementation of a comprehensive and sustainable BRM system.Training must be applicable to local settings and incremental,in a way that participants are not overloaded with information.
